From Brutal (a Jag Tech) =
"DO A HARD REBOOT YOU HAVE TO DISCHARGE THE CAPACITORS IN THE ECU (ALL ECUS, TCU, etc.) AND TO CORRECTLY DISCHARGE A CAPACITOR WHICH IS NOTHING MORE THAN A BATTERY YOU HAVE TO GIVE IT A PATH TO GROUND. TO DO THAT DISCONNECT THE NEGATIVE BATTERY TERMINAL FROM THE BATTERY AND MOMENTARILY TOUCH IT TO THE STILL CONNECTED POSITIVE, THIS GIVES ALL THE CAPACITORS A PATH TO GROUND AND WILL ERASE ALL VOLATILE MEMORY.(CK ENGINE LIGHT CODES ARE STORED IN NONVOLATILE SO THEY NO LONGER ERASE THIS WAY);
If this does not fix your problem, the TCU has failed and needs replacement. A VERY much smaller cause is a wiring harness failure (chaffed, broken).

"dont use sport mode for 300 miles, clear TCM adaptations with hard battery reboot, and there a proceedure to drive involving slow accels to different speeds followed by coasting to complete stops, and avoiding any aggressive driving and downshifting for a few hundred miles, etc."
Normal careful driving usually accomplishes this without the involved driving pattern.
